China's economic growth for the past few decades has been extraordinary. And much of that growth was fueled by real estate – it was like this miraculous economic engine for the country. But recently, that engine seems to have stopped working. And that has raised all kinds of questions not just for China but also for the global economy.

Today on the show, we look at what's happening inside China's real estate market...

When best-selling thriller writer Douglas Preston began playing around with OpenAI's new chatbot, ChatGPT, he was, at first, impressed. But then he realized how much in-depth knowledge GPT had of the books he had written. When prompted, it supplied detailed plot summaries and descriptions of even minor characters. He was convinced it could only pull that off if it had read his books...

The world of economics has these two different sides. One one side, there are the economists in their cozy armchairs and dusty libraries, high up in their ivory towers. On the other, there's the messy world we're all living in, where those economics are actually playing out.

Sometimes, researchers will write about something that they themselves have never actually experienced. Sure, they've thought about it, theorized, come up with smart analyses.....

When Lina Khan was in law school back in 2017, she wrote a law review article called 'Amazon's Antitrust Paradox,' that went kinda viral in policy circles. In it, she argued that antitrust enforcement in the U.S. was behind the times. For decades, regulators had focused narrowly on consumer welfare, and they'd bring companies to court only when they thought consumers were being harmed by things like rising prices...

Earlier this fall, the Federal Trade Commission filed a high-stakes lawsuit against Amazon.

In that suit, the FTC claims Amazon is a monopoly, and it accuses the company of using anti-competitive tactics to hold onto its market power. It's a big case, with implications for consumers and businesses and digital marketplaces, and for antitrust law itself. That is the highly important but somewhat obscure body of law that deals with competition and big business...

You might expect to find economic concepts in the pages of an economics textbook. But you know where you can really see a lot of economic concepts in action? Buffets.

Here at Planet Money we believe there's a lot of economics going on at the all-you-eat buffet, tucked in between the mountains of brisket and troughs of mashed potatoes. From classic concepts like adverse selection, sunk costs, diminishing marginal returns, to more exotic economic mysteries, like the flat rate pricing bias...

Right now, a lot of school districts across the country are making a pretty giant change to the way public education usually works. Facing teacher shortages and struggling to fill vacant spots, they are finding a new recruitment tool: the four-day school week.

Those districts are saying to teachers, "You can have three-day weekends all the time, and we won't cut your pay." As of this fall, around 900 school districts – that's about 7% of all districts in the U.S...

Union membership in the U.S. has been declining for decades. But, in 2022, support for unions among Americans was the highest it's been in decades. This dissonance is due, in part, to the difficulties of one important phase in the life cycle of a union: setting up a union in the first place. One place where that has been particularly clear is at the Volkswagen plant in Chattanooga, Tennessee...

When someone says "the economy is doing well"—what does that even mean? Like, for workers, for employers, for the country as a whole? According to what calculation? How do you put a number on it?

The world of economics is filled with all sorts of "measuring sticks." GDP. Inflation. Unemployment. Consumer sentiment. Over time, all kinds of government agencies, universities and private companies have come up with different ways to measure facets of the economy...

Note: There is swearing in this episode.

In 2017, The University of Minnesota asked comedian Maria Bamford to give their commencement speech. But the University may not have known what it was in for. In her speech, Bamford told the crowd of graduates how much the university offered to pay her (nothing), her counteroffer ($20,000), and the amount they settled on ($10,000), which (after taxes and fees, etc.) she gave away to students in the audience to pay down their student loans...
